Method for establishing a telecommunication link and a telecommunication network

Abstract

A method and a telecommunication network for establishing a telecommunication link between a first and a second subscriber (A, BK) in a telecommunication network, in particular between two devices that are suitable for communicating, with addresses being assignable to the subscribers (A, BK). To provide a reliable telecommunication link between subscribers (A, BK) in the telecommunication network, a switching unit (TR) assigns to the second subscriber (BK) a predetermined number of addresses before establishing the link. The switching unit (TR) then establishes link, and the second subscriber (BK) uses at least one of the assigned addresses when the link is established.

 providing a switching unit (TR) that assigns to the second subscriber (BK) a predetermined number of addresses before the link is established,    establishing the link by the switching unit (TR), and    using at least one of the assigned addresses by the second subscriber (BK) when the link is established.
